OSCILLATING ENGINE.

SPECIFICATION forming part of Letters Patent No. 314,932, dated March31, 1885.

T 0 all whom it may concern.-

Be it known that I, ADAM H. HAFLEY, a citizen of the United States,residing at Ashley, in the county of Washington and State of Illinois,have invented certain new and use ful Improvements in OscillatingEngines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon,which form a part of this specification.

Figure l of the drawings is a side View of my device. Fig. 2 is a planview of the same. Fig. 3 is a vertical transverse sectional View of thecylinder. Fig. 4 is a vertical longitudinal sectional View of the same,and Figs. 5 and 6 are detail views.

This invention has relation to improvements in that class of oscillatingsteam-engines in which reversing mechanism is used, and a steam-chesthaving a flat truly-planed side provided with ports to register withsimilar ports in an oscillating steam-cylinder, the said cylinder alsohaving a plain engaging side, and the ports so arranged as to be readilyconverted into receiving and exhaust ports; and the invention consistsin the construction and novel arrangement of devices, as will behereinafter more fully set forth, and particularly pointed out in theclaim appended.

In the accompanying drawings, A represents the frame of an oscillatingsteam-engine having formed in it the proper vertical bearings a and afor the horizontal shaft B,which carries the crank-wheel I) immediatelyoutside of the bearing a. I

a is an arm of the frame A, extending backward from the bearing a atright angles to the shaft B, and a is an arm curving upward and outwardfrom the frame A at any proper point below the arm a and having at itsend the vertical bearing a parallel to the outer surface of said arm andto the crank-wheel I).

G is the steam-chest fixed to the arm a at a proper distance to the rearof the crank-wheel, and provided with a flat surface, 0, in which itsports open, and which lies in the same vertical plane as the outersurface of the arm a.

0 is a longitudinal partition dividing the steam-chest into equal andsimilar chambers, 0 and 0 respectively, above and below said partition.

0* is a vertical bearing formed in the surface 0 and partition 0, of thesame height as and fellow to the bearing a.

D and d are ports in the chamber 0 situated immediately above thepartition 0, and opening into the front and rear ends of said chamberrespectively. E and e are similar ports for the front and rear ends ofthe chamber 0 situated immediately below the partition 0'.-

F is the cylinder having the flat surface f, equal in size to andfitting closely against the surface 0 of the cylinder. The cylinder ispivoted to the bearings a and c by the studs or trunnions f and frespectively, which stand centrally and at right angles, the latter fromthe surface f, and the former from the opposite side of the cylinder.

f is a spiral spring surrounding the trunnion f, between the bearing aand the cylinder, and serving to press the latter against thesteam-chest, and render the surfaces 0 and f steam-tight.

f 4 and f 5 are ports in the central longitudinal line of the surface f,opening in that surface from the front and rear ends of the cylinderrespectively. The ports f" and f are at such a distance from thetrunnion f, lying between them, that as the cylinder oscillates theformer will successively pass over the ports D and E, in the upper andlower chambers, respectively, and the latter over the ports (1 and e.

f is the piston, and f the piston-rod, connected to the crank'wheel b bythe wrist-pin f.

G is a vertical pipe opening into the top of the upper chamber, 0, andprovided with the escape or exhaust cock 9. H is a similar pipe openinginto the bottom of the lower chamber, 0 and provided with a similarcock, h.

I is a horizontal steam-pipe joining the pipe G at '5, between thecylinder and the exhaustcock g, and J is a pipe extending verticallydownward from I for a sufficient distanceand then bending at rightangles and joining the ICO z is a throttle-valve in the stcam'pipe I, atany proper point between the pipes J and G, and j is a similar valve atany proper point in the pipe J.

K is the boiler, to which the steam-pipe I is attached at 70. k is apipe passing from said boiler and coiled longitudinally in thewater-tank L, and k is a cock between said tank and the boiler.

L is a feed-water-heatin g tank formed of-two equal and similar endportions united so as to be watertight by the flanges Z Z and bolts Z Z,820., and containing the coiled pipe 7c, the end of which opens withinsaid tank.

Z is. a plug in one end of the tank, which is removed when it becomesnecessary to refill the same.

Z. is a feed-water pipe connecting the tank and boiler, and controlledby the cock F between them.

.Ihe operation of the different parts of the mechanism is as follows: Itbeing desired to run the crank-wheel b forward, the throttle z andescape-cock h are closed, and the throttle j and cock 9 opened. Steamwill then enter wheel I) will reverse.

the cylinder, when it begins to oscillate by way of the pipe J, lowerchamber, 0 and ports E and e of the same acting as steam-ports, and thecylinder will exhaust by way of the ports D and d and' the upperchamber, 0 through the cock 9, the crank-wheel b at the same time beingdrawn forward. Upon closing the throttle j and cock 9 and opening thethrottle z" and cook h the steam will enter the upper chamber, 0 theports D and d of which act in this case as steanrports. The exhaust willtake place through the ports E and e, the lower chamber, 0 and cook h,and the crank- It must be observed that when the cylinder takes steamfrom the port at one end of one chamber it exhausts by the port at theother end of the other chamber, and the reverse.

When it is desired to make use of the tank L, the cock is of the pipe Jois opened, allowing the steam to escape from the open end thereof intothe water in said tank and heat the same. When this is accomplished, thecock k is closed, and the cock Z in the pipe Z is opened to feed theboiler or the cock Z" may Having thus described myinvention, what Iclaim, and desire to secure by Letters Patent, is

In an oscillating steamengine, the combination, with the steam-chesthaving the bearing 0, of the arm f the upwardly and forward] y curvedarm a the steam-cylinder having the trunnions adapted to be supported bythe said bearings, and th'e'spring f arranged upon the trunnion f, andengaging the inner side of-the said. curved arm a, to keep the cylinderpressed tightly against the steam-chest and form a steam-tight jointtherewith, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
